6.36.1 Detailed Description

Like the class ABA_NUMVAR for variables we provide the class ABA_NUMCON for constraints which are uniquely defined by an integer number.

Parameters:

int

number_ The identification number of the constraint.

6.36.2 Constructor & Destructor Documentation

6.36.2.1 ABA_NUMCON::ABA_NUMCON (ABA_MASTER * master, const ABA_SUB * sub, ABA_CSENSE::SENSE sense, bool dynamic, bool local, bool liftable, int number, double rhs)

The constructor.

Parameters:

master

A pointer to the corresponding master of the optimization.

sub

A pointer to the subproblem associated with the constraint. This can be also the 0-pointer.

sense

The sense of the constraint.

dynamic

If this argument is true, then the constraint can be removed from the active constraint set during the cutting plane phase of the subproblem optimization.

local

If this argument is true, then the constraint is considered to be only locally valid. As a local constraint is associated with a subproblem, sub must not be 0 if local is true.

liftable

If this argument is true, then a lifting procedure must be available, i.e., that the coefficients of variables which have not been active at generation time of the constraint can be computed.

number

The identification number of the constraint.

rhs

The right hand side of the constraint.

6.36.2.2 virtual ABA_NUMCON::~ABA_NUMCON () [virtual]

The destructor.

6.36.3 Member Function Documentation

6.36.3.1 virtual double ABA_NUMCON::coeff (ABA_VARIABLE * v) [virtual]

Returns:

The coefficient of the variable v.

Parameters:

v

The variable of which the coefficient is determined. It must point to an object of the class ABA_COLVAR.

Implements ABA_CONSTRAINT.

6.36.3.2 virtual void ABA_NUMCON::print (ostream & out) [virtual]

Writes the row format of the constraint on an output stream.

It redefines the virtual function print() of the base class ABA_CONVAR.

Parameters:

out

The output stream.

Reimplemented from ABA_CONVAR.

6.36.3.3 int ABA_NUMCON::number () const [inline]

Returns:

Returns the identification number of the constraint.

Definition at line 130 of file numcon.h.

6.36.4 Friends And Related Function Documentation

6.36.4.1 ostream& operator<< (ostream & out, const ABA_NUMCON & rhs) [friend]

The output operator writes the identification number and the right hand side to an output stream.

Returns:

A reference to the output stream.

Parameters:

out

The output stream.

rhs

The variable being output.
